lJdLSld DAYTON, OHIO, ASSIGNOR TO FRIGIDAIRE CORPOBATION, OF DAYTON, OHIO, A CORPORATION OF OI-IZO COLLAPSIBLE STAND Application filed July 13,

This invention relates to collapsible stand and particularly to portable stands. I

One or" the objects of the present invention is to provide a strong stand which will be light in weight and which may be collapsed and folded into a small compact bundle.

' Another object of the invention is to construct a collapsible stand of material which will not be affected by climatic changes.

More specifically it is an object of the invention to provide a collapsible stand which will serve either as a motion picture screen or an illustrating device for charts or the like.

Further objects and advantages of the present invention will be apparent from the following description reference being had to the accompanying drawings, wherein a preferred form of the invention is clearly shown.

In the drawings:

Fig. 1 is a front elevational view of my improved collapsible stand.

Fig. 2 is a side elevational view thereof.

Fig-3 is a sectional view taken on the line 33 of Fig. 2 showing the stand supporting members.

Fig. l'is an enlarged sectional view taken on the line 4-l of Fig. 1 showing a hinged connection of one of. the lower braces and the detachable connection of one of the upper braces.

Fig. 5 is an enlarged vertical section thru the standard taken on the line 55 of Fig. 1.

Fig. 6 is an enlarged horizontal section taken on the line 6-6 of Fig. 1.

Fi 7 is an enlarged vertical section taken on the line 77 of Fig. 1.

Figs. 8, 9, 10 and 11 show various parts of the stand with the braces secured thereto collapsed, and

Fig. 12 is a view of a portable bundle which contains all the collapsed parts of the stand shown in Figs. 8, 9, 10 and 11.

Referring to the drawings, 10 designates a standard comprising detachable portions 11 and 12. Portions 11 and 12 of the standard are preferably made of hollow tubular metal and have their ends slotted as at 13 to receive brackets 14 and 15 mounted on angle iron cross-pieces 16 and 17 providing-out- 1929. Serial No. 378,188.

wardly extending arms which are adapted to be secured to the standardlO. Lower portion 12 of the standard has its upper end threaded to receive internal threads provided on the upper portion 11 of the standard. The angle iron cross-piece l? is firmly secured to the standard 10 by threading the portions 11 and 12 tightly together. Figures 5 and 6 more clearly show this method of securing the angle iron cross-piece 17 to the standard 10. Angle irons l8 and 19 hinged to the lower end of the standard 10 by pin QOeXtend outwardly and have angle iron members 21 and 22 disposed at right angles thereto and hinged at 23 for supporting the stand.

I The upper angle iron 16 has brackets 25 secured thereto from which a roll screen 26 is dependingly supported. The screen 26 is painted white and is similar to the ordinary window shades used in houses and serves as a screen upon which pictures or illustrations may be projected. Hooks 27 mounted on suitable fabric straps 28 which are secured to the angle iron 16 provide a mounting for dependingly supporting display charts. A

writing pad may be-supported 0n the hooks.

2? when it is desired to use the stand for illustrating purposes other than by the display charts. The rivets which secure straps 28 to the angle iron 16 also secure a lattice 29 thereto- The location and method of securing the screen 26, hook 27, straps 28 and lattice 29 is more clearly shown in Fig. 7. The lattice 29 comprises a plurality of narrow siats 290; held together by cords 29?) alternately woven therearound. The lattice provides a backing for display charts or for a writing pad which may be suspended from the hooks 27 thereby preventing puncturing of the charts while illustrating with pointers or the like. i

To render the stand more rigid I have provided a plurality of strap iron braces which may be hinged or pivoted to the various parts of the-stand and which are adapted tb be collapsed and rolled up with other parts thereof. I provide a brace 31 on each side of the standard 10 having their upper ends pivoted or hinged to the ends of the angle iron crosspiece 16 and their lower ends detachably connected with studs 32 secured to the ends of the lower angle iron cross-piece 17. The stuos 32 are provided with a shank portion 34 adapted to receive slots provided in the braces 31. The l races 31 are also provided with hinged joints 236 which permit these braces to be collapsed and folded adjacent the angle iron cross-piece 16. Braces 38, pivoted or hinged to the angle iron crosspiece 17 are twisted so that slots 39 at the ends thereof will engage studs 4L0 located on the angle iron members 21 and 22. The angle iron members 21 and 22 have b aces 11 pivot ed or hinged thereto and provided with slots -2 adapted to engage studs l?) located on the braces 38 below the twisted portion thereof. All the braces are made slightly shorter than the distance between their connecting points so that they will be und slight tension when assembled thereby provid rigidv structure. The hinged. connocti of the braces with the various other parts of the stand permit them to be folded and relled into a compact portable package.

"iahen it is desired to move the stand from one locality to another it may be disassembled and rolled into a compact package.

Dismantling of the stand is accomplished in the :t'ollowing manner. Braces 31 are manipulated so that slots therein move out of engagement with the studs Hinged joints 36 inthe braces 31 then permit the braces to be folded against the angle iron crosspiece 16. The crosspiece 16 carrying the screen 26, supporting hooks 27 and thelattice 29 maythen be remofed irom theupper end of standard 10. (See 8.) After the crosspiece 16 has been dismantled the upper portion 11 of standard 10 may be unscrewed from the lower portion 12. (See Fig. 9.) The separation of portions 11 and 12 of the standard 10 then permits the removal of angle iron crossiece 17 from the standard. To remove the cross-piece 17 braces 41 must be manipu lated to disengage slots 42 formed therein from studs a3. Braces 38 are then manipulated to disengage slots 39 formed therein from the studs ll) secured to angle iron member 21 and 22. Braces 38 are then folded against the cross-piece 17 and removed therewith from the portion 12 of the standard (see Fig. 10). There now remain only portion 12 of the standard and the standard supporting members to be collapsed. The braces 41 now being tree are folded against angle iron members 21 and which are hinged to the angle irons 18 and 19. The members 21 and 22 are then moved about their hinge 23 so as to be in alignment with the angle irons 18 and 19. This movement is shown by the dotted line positions of members 21 and 22 in Fig. 3. The angle irons 18 and 19 are then moved upwardly about their hinge 20 so as to be in alignment and ainst the portion 12 of the standard 10 (see Fig. 11). The collapsed parts of the stand shown in Figs. 9, 10 and 11 are then placed upon the lattice 29 and rolled into a compact bundle. The lattice 29 is of suilicient length and width to completely enclose all collaosed parts of the stand including the cross-piece 16 to which the lattice is secured thereby providing a cover for the bundle It desired a separate water proof cover may also be provided for the bundle.

The cre sectional. contour of the cross-piece stand. are made of as light a material as obtainable so that the bundle or package will not no excessive in weight. Likewise I have ovided a collapsible stand 01"? such con- .j-crnction that will eliminate non-fitting of the various parts due to climatic changes While I have described the operation of dismantling the stand it will be understood by those skilled in. the art that the setting up or assembling operation is accomplished in reverse order to that described. It is apparent from the foregoing description that I have provided a novel stand which may be used by salesmen, lecturers and demonstrators either as motion picture screen, black board or display device and which may read ily he collapsed and carried from one 10- cality to another.
